We log ship some databases to above cluster, or will be, we're setting up/testing this now. I've run into a problem trying to run command line of sql backup (SqlBackupC.exe).
We only use default instances, don't have any sql servers with a named instance. On our current servers (not the cluster ) we can run :
SqlBackupC.exe -SQL "RESTORE LOG [DB] FROM DISK = [E:\\backup\\DB_10140108_123550_LOG.sqb]
WITH STANDBY = [E:\\backup\\StandByFiles\\DB.dat], PASSWORD = [DBPWD], MOVETO=[Complete\\db]" -E

and will run fine.
If I run same script on our cluster, I get error
SQL error 17: [DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or access denied.

1/9/2014 7:48:51 AM: Failed to connect to SQL Server instance:

My user account is a sys admin on this sql. It looks to me like it is trying to use machine name as name of sql server, so trying to connect to sql named: serverA, we don't have that, since is cluster, sql is called sql_cluster. In trying to force it to connect to proper sql name, I looked for a -S or some parameter to pass in server name, but only saw -I for instance name. if i try -I and put in sql_cluster, it fails, looking for server: serverA/sql_cluster, we don't have named instance like that so that fails.
If a use -I (local) it works,
Somehow it uses different method to find sql server name if I omit it, different than if I pass -I (local) ? That seems strange, so maybe I'm missing something? I would expect all clusters to have this make up, where have 2 + servers, and sql on it but w/ diff name than the actual server name. Might our cluster not be set up right?
